    6 ARC Gas Guns

    Correct. The Factory loads were Chrono'd and came right into the <2600 fps range. Edit to add: I had wanted to work up to max load with Lever, since I'd read where numerous people say the SDs are not great until you get close to max case density in the case and then the SDs come right down...

    Yep, that's what I'm thinking as well.

    6 ARC Gas Guns

    This chart really helps - thanks! And that explains a lot and creates more questions now. My first test with loading for the 6 ARC, I was getting much higher speeds than I expected, along with early pressure signs that I didn't expect. Npw the trick is to figure out why... Below are the...

    Neck Tension and Pressure Signs

    I had all the same issues.... I was blowing primers and getting swipe at loads that had previously shot well and were definitely not super hot. My eventual remedy was two-fold. I found the necks in my Lapua brass were a bit tight in my match chamber (drop in Proof barrel for an AI-AT). So I...

    6 ARC Gas Guns

    Hi All - just starting to load for my 6 ARC 18" Proof barrel with an adjustable JP Gas block. Question 1, what speeds are a good target range with 105-108gr bullets to try to get to for general steel at 800-1K? The Hornady factory ammo I've shot through it so far seems to run in the mid to...

    Bolt gun Load development - with or without a suppressor?

    Sounds good. Ive been doing that for a while (load Dev with the can on) and have had no issues. I just was curious what the prevailing wisdom was. Thanks!

    Bolt gun Load development - with or without a suppressor?

    Thanks! That's been pretty much my attitude as well. "Train like you fight". I just wanted to make sure I wasn't missing something that was hampering my load dev and causing issues.

    OCW Guys… help me read these!

    Ok, so I've read through this entire thread, I read the entire outdoor life article and have read here and elsewhere where numerous credible people have claimed that small sample size ladder or OCW tests are essentially invalid. My own belief is that "natural dispersion" is barrels in a...

    6mm Dasher

    Thanks, yeah I'm well aware that someone's hand loads should always be taken with a grain of salt. I'm just trying to get an idea of common loads, bullet/powder combos, avg MVs, etc that have worked for others. I've done that with other calibers using SH member info with good success. It...

    Bolt gun Load development - with or without a suppressor?

    Is it recommended or not to shoot your load develpment ladders/OCW with the can on if 90% of your shooting will be suppressed? Or is it better to find the load without the can and then tweak as necessary from there?

    6mm Dasher

    Hi all, I just dove into the deep end of the 6 Dasher pool. I have a Proof drop in Ai-AT barrel, 200 pieces of Alpha brass and dies on the way. I've got good stocks of Berger 105 Hybrid and 109 LR hybrid as well as 107 SMKs. For powder, I have lots of Varget, 4166, H4350 and 4451. Primary...

    6 ARC load recommendations- 18” AR

    Hi all. I did a search here by found very little info on 6 ARC load data. I’m just getting ready to dive into the loading process and any info would be much appreciated. I built an AR w/ a PROOF 18” stainless. So far it shoots well out to 1k with factory Hornady 108 ELDM loads. My plan is to...

    What scope is everyone running for elr

    That's very interesting, thank you for that. Takes all (or most) of the user subjectivity out of the equation. As it should.

    Proof Research gas ports undersized?

    Ok, I'll try that before I send it back. Thanks!

    6mm ARC extremely dirty?

    Holy crap!!! I did a carbine course with well over 1500 rounds (probably 2K) over a weekend with no cleaning and it wasn't a quarter as dirty as that.

    Proof Research gas ports undersized?

    Ah sorry, you are correct. It's an 18" +1 gas system, not +2. On the other stuff, I'm pretty content that all of the components are top end and brand new. The BCG, type 2 Bolt, adjustable Gas block, buffer and spring are all new JP components. The Gas tube is Proof's that came with the...

    Proof Research gas ports undersized?

    Sorry, that's BS to attack the poster for not reading instructions. I'm having the exact same issue on an 18"+2 gas system. I wrote to Proof and they were initially super helpful and responded right away to try a bunch of different things. Obviously they suggested checking the gas block...

    Carbon ring removal

    It's probably been answered elsewhere, but what causes the carbon ring and is there anything to do to prevent it or slow it down? Is it from the Case necks being oversized and not allowing it to form a seal? Or just the nature of the game?

    **6 Creedmoor**

    No experience with the N540, but I'm having amazing success with IMR 4451 and 105 Hybrids in both my 6 CM Bolt (AI AT - Proof barrel) and my new JP 6CM upper. My bolt gun also really loves the 109 LR Hybrids with 4451 as well. I find that powder is a great substitute for H4350 and is typically...

    6 ARC dies - what do you recommend for precision loading?

    Last question..... does the 6 PPC seater die work well for the ARC? I've seen some other posts that reference using that die as a substitute. Just wondered if anyone has tried it and what the results are.
